SUBJECT: Evaluation of Safety Lanyard
2. RESULTS:
a. Length: The lanyard to include hardware measured approximately 26” min and 35”
max. length. Without accounting for hardware, the Safety Lanyard adjusted to 18”
min. and around 27” max.
b. Proof Load Test: Twenty (20) lanyards environmentally conditioned passed proof
load test with no defects. All hardware release mechanisms worked after testing.
However, there was a moderate amount of superficial fraying and the rubber sheath
ripped (see Figure 3). The Prusik knot deployed at approximately 1,000lbs.
c. Failure Load Test: Five (5) systems were taken to failure load (see figure 4 and
5). Overall Break Strength average was 4,149.5 lbs.
d. Confirm one hand operation of platform connector hardware without visual aid.
e. Lanyard metal components are a solid, smooth finish and free of manufacturing defect, burrs
or uneven surfaces.
f. Lanyard markings are clearly and permanently labeled (see figure 6).
